BOILER-TRUCK.

Patented June 18, 1907.

Application filed March '27, 1906. Serial No. 308,356.

To aZZ whom it may concern:

Be it known that we, WILLIAM T. FIERs and BENJAMIN F. TIGNER, citizens of the United States of America, residing at Redkey, in the county of Jay and State of In-. diana, have invented new and useful Improvements in Boiler-Trucks, of which the following is a specification.

This invention has for its object to provide a truck whereby boilers may be conveniently transported from place to place and also supported while in use, the device being especially designed for transporting and supporting steam boilers in oil fields and lumber regions, where steam boilers are moved from place to place at more or less fre quent intervals to supply power for operating drills, pumps, saws and other machinery.

The device is adapted to firmly support the boiler without the necessity of riveting or otherwise rigidly fastening the boiler to the truck frame, and to permit of the ready removal of the boiler, when it is desired to mount it on a stationary bed.

In the accompanying drawing,-Fi gure 1 is a side elevation of a boiler mounted upon my improved truck, the parts of the latter being shown in longitudinal section. Fig. 2 is a front elevation of the same. Fig. 3 is a top plan view of the rear frame of the truck.

The truck comprises in its construction front and rear frames A and B. The front frame A consists of an axle 1 carrying su porting wheels 2 and a bolster 3 pivotally mounted thereon between the wheels.

Supported on the bolster is a support 4 of segmental form or corresponding in contour to the forward end of the body of the boiler. The support is pivotally connected with the bolster by a king bolt 5, thus permitting the axle and wheels. of the forward truck to turn in either direction for steering purposes. The rear truck B comprises an axle 6 carrying supporting wheels 7. Pivotally connected at one end to the axle are hanger'plates 8 connected at their the lower portion of outer or forward ends by a tie rod or bolt 9,,

thus forming a forwardly projecting frame to support the rear portion of the boiler.

The forward portion of the body 0 of the boiler is designed to rest upon the supporting seat 4, while the rear portion of the fire box C of the boiler bears against the axle 6 and rests at its base upon the tie rod 9 of the rear truck, the wheels of the trucks being of proper relative size to support the boiler in a horizontal position. It will be observed that the hanger plates 8 project at a downward and forward angle from the axle to position said axle and tie rod 9 to support the rear portion of the boiler in the manner described.

The trucks are fastened to the boiler'by yokes, each consisting of a saddle rod 10 resting upon the top of the boiler and connecting rods 11 hooked or otherwise constructed at their lower ends to engage the supporting portions of the trucks, the said rods 11 being connected with the saddles by turn buckles 12 to adapt the yokes to be adjusted to tightly clamp the boiler in applied position and to permit of the ready detachment of the yokes when it is desired to remove the boiler from the truck. As shown, the rods 11 of the front yoke are attached to the upper ends of the seat support 4, while the corresponding rods of the rear yoke are attached to the plates 8 of the rear truck frame, whereby the front and rear portions of the boiler are firmly connected with the respective frame. The front and rear yokes are preferably arranged in rear of the smoke stack C and in front of the steam dome C in order that these parts of the boiler will act as stops to prevent any possibility of rearward shifting of the boiler on the truck frames.

In order to ing forwardly on the truck frames and to more securely fasten the boiler in position, a bracing rod 13 is arranged to connect the boiler with the front truck frame, said rod being formed at its rear end with an eye 14 to pivotally engage the king bolt 5, and at its forward end with a hook 15 to engage the front edge or flanged portion of the body of the boiler. A stay rod 16 also connects the front truck frame with the rear portion of the boiler. This rod is composed of two sections connected by a turn buckle 17, the front section being provided at its forward end with an eye 18' to engage the pivot bolt 5, while the rear section hook 19 to engage the flange around the mud ring at the forward edge of the fire box of the boiler. These bracing or stay rods not only prevent the boiler from shifting forwardly but increase the stability of the support.

The device may be drawn or pushed in any preferred manner to transport the boiler from place to place, and steering may be readily efiected by the pivotal connection of is provided with a' prevent the boiler from shiftthe front truck frame with the rigidly held seat support 4. The trucks may support the boiler While in use or be simply employed as a means for conveniently moving the same from one point to another, and it will be understood that by simply disconnecting the turn buckles 12 of the two yokes, the boiler may be conveniently detached from the irames for transfer to a suitable supporting Having thus described the invention, what is claimed as new, is

1. Adevice of the character describedcomprising front and rear wheeled frames adapted to support the front and rear portions of a boiler, the rear wheeled frame comprising an axle adapted to bear against the rear of the boiler, plates pivotally mounted on said axle, a rod connecting the free ends of said plates adapted to extend under the rear portion of the boiler, a yoke connected with said plates to attach said rear wheeled frame to the boiler, said yoke being adapted to bear upon the front portion of the steam dome of the boiler to hold said frame against rearward movement, and means for connecting the front wheeled frame to the boiler.

2. A boiler truck comprising a front Wheeled frame, a rear wheeled frame, said frames being adapted to support the front and rear endsof a boiler, means for connecting said frames with the body of the boiler, and rods connected with the front wheeled frame and provided with hooked ends to respectively engage the flange at the front end of the boiler and. the flange at the lower forward edge of the firebox.

3. Adevice of the character described com prising front and rear wheeled frames, said frames being adapted to support the front and rear portions of aboiler, means for connecting the front wheeled frame with the boiler, means for connecting the rear wheeled frame to the boiler, and braces extending from said front wheeled frame and having portions to respectively engage the flange at the front of the boiler and the flange around the mud ring at the forward edge of the fire box of the boiler.

4. Adevice of the character described comprising front and rear wheeled frames having frame supports for the front and rear portions of a boiler, rods extending from said frame supports, yokes adapted to engage the top portions of the body and fire box of the boiler, turn buckles connecting the respec tive yokes with the respective rods of the frames, and stays for connecting the front wheeled frame with the front end of the boiler body and lower front. portion of the fire box.

5. A boiler truck comprising a front wheeled frame, a rear wheeled frame, means for connecting said frames with the body of the boiler, and brace rods carried by the front wheeled frame and having hooked ends to engage the flanged portions upon the front and rear of the boiler.

6. A device of the character described comprising front and rear wheeled frames, the front wheeled frame having a saddle pivotally connected therewith, and the rear wheeled frame being provided with a pivoted supporting portion adapted to engage under the lower rear end of the fire box, yokes for respectively connecting said saddle and pivoted supporting portion of the rear wheeled frame with the b ody and firebox of the boiler, the yoke of the rear wheeled frame being adapted to engage the steam dome and hold said frame from rearward movement, and bracing rods connected with the front wheeled frame and extending forwardly and rearwardly therefrom, said rods being provided with hooked free ends for respective engagement with the front flanged end of the body and the flange at the lower forward end of the fire box.

7. A boiler truck comprising a front wheeled frame, a rear wheeled frame, said frames being adapted to respectively support the front and rear ends of a boiler, the rear wheeled frame being provided with pivotally mounted depending plates and a rod connecting said plates at their lower ends, said rod being adapted to extend beneath the lower rear end of the boiler, rigid yokes for connecting said frames with the body of the boiler, and braces for connecting the front wheeled frame with portions of the boiler in front and rear thereof.

In testimony whereof, we affix our sign atures in presence of two witnesses.
